Product Overview

Arista’s DCS-7280SR2A-48YC6 series of switches deliver high-density 25 GbE host connectivity coupled with 100 GbE uplinks, built for modern data-centre leaf or top-of-rack deployments. Designed to support mixed-speed server links and high-throughput aggregation, this family provides the throughput, scalability and workflow flexibility expected in enterprise and cloud-scale fabrics.

Ideal deployment/environment: Hyperconverged server racks, virtualised storage clusters, or cloud-scale data centres needing dense 25 GbE server access with 100 GbE uplinks. Well-suited as leaf or ToR switches in leaf-spine fabrics, providing mixed-speed connectivity, high throughput, and flexible memory footprint (for large routing/FIB tables).
